: Help someone!: Please explain the process/materials to consider when attempting a leak free shower remodel - specifically, we intend to replace a fiberglass surround with tile (shower stall only). : We prefer not to use a fiberglass (or other) pan for the base. Instead we'll continue with our cermamic tile. Do we need to install a rubber backing (under the cement board) and, if : so, what's it called? Also, how high should we build the "curb" ? Thanks in advance for any and all advice!

The curb should be 2". If you are installing a new pan you will need an adjustable shower drain and a water proof membrain on the sub floor fold up the corners 6" up the wall. Use no nails. Use wonder board (concrete board) on walls. use concrete and tile on the floor with 1/4" sloap to the drain. Dale Plumbing Service LMP
